This happening to anyone else?

I use lots of third-party Twitter apps. My favorite has to be TweetDeck, so easy to use! However, my bread and butter of Twitter checking is done through the main page. I've noticed for the last month or so, that sometimes @messages have a severe delay. They show in your @message display correctly, however - you might have received a message 10 mins ago that will fall to the bottom part of the page by the time it shows up, and you never even saw it!

Anyone know what I'm talking about? Have it happen to them?! Feel free to keep stalking me if I don't reply back ...
